The invention relates to the technical field of electronic circuits, in particular to an electronic fuse, a vehicle body controller and a vehicle. The electronic fuse comprises a switch chip, the switch chip is provided with a first register VOCTHRS and a second register T-NOM, the first register VOCTHRS is used for setting a current parameter, the current parameter represents the maximum value of continuous current borne by a loop, the second register T-NOM is used for setting a response time parameter, the response time parameter represents response time corresponding to each current value for triggering turn-off, and the first register VOCTHRS and the second register T-NOM are connected with the first register T-NOM; the switch chip is configured to generate a current protection curve according to the current parameter and the response time parameter; acquiring a current value of the loop; determining a response time parameter corresponding to the current value according to the current value and a current protection curve; when the duration of the current value exceeds the response time parameter, the loop is disconnected. The electronic fuse can flexibly configure parameters of the register according to actual working condition requirements, a more appropriate current protection curve is obtained, and the circuit is more flexibly and intelligently protected.
